Abstract: This invention relates to a multiplex control of components and subsystems in motor vehicles having: a central electronic control unit and multiplex bus electronic units (3) associated with each component and each subsystem. The multiplex bus electronic units (3) are incorporated in the casings (2) of the connectors, the same having on the component side (2b) the requisite number of contacts and on the back a four-pole multiplex connector (1, 2a) for two signal lines and two power lines.

Abstract: Combined beam waveguide and metal cable plug connectorA combined beam waveguide and metal cable plug connector with an angled cable outlet, comprising a housing (1) in which beam waveguide plugs (4) and flat contact springs are disposed on the plug side in contact chambers (2, 3) provided for the purpose while an outlet aperture for the cables (5, 21) is provided at the rear. The opening for the cables comprises a channel (6), the base of which is bent at an angle of 90.degree. maximum to the plug axis and which is open towards the back of the plug connector. The metal cables (21) are taken out of the housing (1) in one or more layers on the channel base (6). A snap cap (7) closes the channel (6) at the rear and has lateral ducts (8) in which beam waveguide cables (5) are accommodated, the ducts (8) ensuring that the beam waveguide cables (5) are deflected with a radius which is not damaging to the beam waveguide cables.

Abstract: An electrical spring contact having an inner spring contact with an inner spring base and inner spring arms. A box-shaped outer spring with an outer spring base and outer spring arms is connected to the inner spring base of the inner spring. The outer spring arms are bent inwardly in a funnel-shaped way at the plug-in end, and the inner spring and the outer spring are formed by molded sheet metal parts. The outer spring has a bending slot extending across its total length, and the spring contact is insertable in a chamber of a receiving casing and arrestable in the latter by holding members. The lateral surfaces of the outer spring extending between the two outer spring arms are provided with recesses bordered by support surfaces. The support surfaces are axially supported by holding members projecting into the chamber of a receiving case.
